"Naked Bea Arthur," a painting by John Currin was sold at a Christie's Auction on Wednesday for $1.9 million to an anonymous buyer. The controversial painting of Bea Arthur is being flagged on Facebook.

The "Bea Arthur Naked" painting from 1991 was actually expected to sell for as high as $2.5 million. A secret bidder acquired the work at Christie's Post-War and Contemporary Art Sale in New York City last night for $1.9 million. The Christie's auction netted a whopping $495 million for 70 lots on the block.

Jean-Michel Basquiat's "Dustheads," circa 1982, notched a new record for the late legendary artist with a sale of $48 million to Warner Music Group Group mogul Len Blavatnik.

The naked painting of Dorothy from "The Golden Girls" has been banned from Facebook. The artwork showing Bea's breasts is apparently too racy for its members. The site's terms of service technically forbid nudity, but not in art. So the decision is controversial and may be reverted soon.

Here's what critics have said about "Bea Arthur Naked"

"Boycott this show." (Kim Levin, The Village Voice, 1992)

"There are critics and other art world luminaries who find Currin's art, though technically admirable, to be derivative, extremely vulgar, and downright quirky." (Frederick Winship, UPI, 2004)

"A graduate of Yale's art school, Currin can paint, however, no better or worse than dozens of others." (Peter Goddard, Toronto Star, 2004)

Others put it differently:

"Those middle-aged women are not objects of mockery, as it happens, but memorable in their proud desperation to keep up appearances, and dignified in the case of the actress Bea Arthur bare-breasted." (Michael Kimmelman, New York Times, 2003)
